Host plants:
The larva feeds on Sarcopoterium spinosum (Rosaceae).
Habitat:
Mattia callidaria inhabits open and often grazed habitats, especially the Mediterranean garigue with occurrence of the host plant.
Life cycle:
The moths usually fly in October and November. The larvae develop over winter and are mature in early spring. I could beat them abundantly in Cyprus (Paphos) in late February 2017. The pupa aestivates.
Remarks:
Mattia callidaria occurs in the Eastern Mediterranean (S-Greece: especially Peloponnese, Crete, some Eagean Islands as e.g. Samos; S-Turkey; Cyprus; Levante).
